4. A solar inverter for outdoor use and easy maintenance and a method for using the same according to claim 3, characterized in that: A clamping slot is provided inside the rear fixing plate, and the fixing rod is buckled inside the clamping slot.

5. A solar inverter for outdoor use and easy maintenance and a method for using the same according to claim 4, characterized in that: Two front fixing plate groups are respectively arranged at the upper and lower ends of the front cover, and a rear fixing plate is matched and arranged on the rear box body corresponding to each front fixing plate group.

6. A solar inverter for outdoor use and easy maintenance and a method for using the same according to claim 1, characterized in that: The guide groove is arranged on the inner side of the limiting frame.

7. A solar inverter for outdoor use and easy maintenance and a method for using the same according to claim 1, characterized in that: A through hole is formed through one side of the mounting frame, and two through holes are provided.

8. The solar inverter for outdoor use and easy maintenance and the method for using the same according to claim 1, characterized in that: The outer wall of the mounting plate is matched with the inner wall of the connecting groove, and the outer wall of the roller is fitted with the inner wall of the sliding groove.

9. A solar inverter for outdoor use and easy maintenance and a method for using the same according to claim 1, characterized in that: A protective mechanism is provided on the top of the mounting frame, and the protective mechanism includes a slot, a second bolt, a support frame, a second pin hole and a cover plate. A slot is provided on the top of the mounting frame, a second bolt is threadedly passed through one side of the slot, a support frame is inserted into the inner side of the slot, a second pin hole is provided on the outer side of one end of the support frame, a cover plate is fixedly connected to one end of the support frame, and the support frame is fixedly connected to the mounting frame by the second bolt, and the inner wall size of the slot is adapted to the outer wall of one end of the support frame.

10. A method for using a solar inverter for outdoor use and easy maintenance, characterized in that: The solar inverter according to any one of claims 1 to 9, wherein the steps are: (1) Now install the rear box to the preset fixed position; (2) Use bolts to penetrate the through holes on one side of the mounting bracket, and use bolts to fix the two mounting brackets to the wall; (3) Then, insert the two mounting plates on the back of the rear box into the connection grooves from top to bottom, and use rollers to roll the connection grooves to install the rear box; (4) After the plugging is completed, the first bolt is tightened so that one end of the first bolt is inserted into the first pin hole, thereby limiting the mounting plate so that the outer wall of the mounting plate is matched with the inner wall of the connecting groove, ensuring that the rear box body does not shake after the installation is completed; (5) After the rear box is installed, insert one end of the support frame into the slot, then screw on the second bolt, and insert one end of the second bolt into the second pin hole, so as to limit and fix the support frame, and one end of the support frame 14 is fixedly connected to the cover plate, and the rear box is protected by the cover plate; (6) Install the solar inverter body into the rear box; (7) After the solar inverter body is installed, it is closed to the rear box through the front cover. The guide block on the front cover matches the corresponding guide groove. Then the front cover and the rear box are fitted together and sealed with a sealing gasket. (8) When the front cover and the rear box body are matched, the multiple front fixing plate groups on the front cover will be buckled on the outer side of the rear fixing plate; (9) When sliding to the specified position, the fixing rod between the two front fixing plates will be buckled with the inside of the rear fixing plate to fix it. At the same time, the torsion spring will drive the buckling plate to buckle with the outer side of the buckle rod through the connecting rod and the connecting plate, thereby limiting the position of the front fixing plate; (10) When maintenance is required, press the pressure plate so that the limit rods on both sides of the pressure plate engage with the inside of the snap plate, thereby separating the snap plate from the buckle rods, making it easier to disassemble and assemble the front cover and maintain the inverter in the rear box; (11) When the inverter needs to be disassembled as a whole, based on step (10), first disassemble and remove the inverter from the rear box, then just unscrew the first bolt, drag the rear box upward, and take out the rear box using the rollers, which facilitates the disassembly of the rear box.
